Error log about the crash

When trying to play games like Dota, Darkest Dungeon or any game that uses particle animations (as I supose that is causing it), the computer crashes and can only be recovered by a hard reset.
I've already posted at Manjaro (https://forum.manjaro.org/t/xorg-freezes-when-playing-dota/25938/11) more details about this issue, but it's getting worse everyday.
